INVENTOR PLASTIC N OZZLE MOUNTING John Hen-chart, River Forest, 111., assignor to Continental Can Company, Inc, New York, N. Y., a corporation of New York Application April 17, 1956, Serial No. 578,668

6 Claims. (Cl. 222-566) The invention relates generally to metallic receptacles and primarily seeks to provide a sturdy plastic nozzle mounting which is neat in appearance, liquid tight, secure against turning of the nozzle when screw closure caps are applied thereon, and devoid of presentation of raw metal body or edge portions either internally or externally of the container.

An object of the invention is to provide a nozzle mounting of the character stated wherein the container breast has an upstanding neck in which the tubular plastic nozzle is inserted and through which it projects, said neck being connected with the breast through a well rounded curve firmly abutted and covered by a flange projection at the lower end of the nozzle, the upper end extremity of the neck having an inwardly turned edge embedded in the outer surface of the nozzle body, and said breast and flange at the opposing portions thereof surrounding the neck having cooperatively engaging recess and protuberance equipments effective to prevent turning of the nozzle in the neck when closure caps are applied thereon.

Another object of the invention is to provide a plastic nozzle mounting of the character stated wherein the cooperatively engaging recess and protuberance equipments are in the form of dimples indented inwardly from the breast and which deform the nozzle flange and provide the recesses therein, the embedding of the upper end extremity of the neck in the outer surface of the nozzle body serving not only to prevent presentation outwardly of the raw metal edge of the neck but also to secure the nozzle in position in the neck with its flange firmly contacting the interior surface of the breast with the breast dimples embedded in the flange.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.

In the drawing:

Figure 1 is a side elevation and partial vertical secfional view of the polyethylene nozzle of the assembly.

Figure 2 is a fragmentary sectional view illustrating the nozzle receiving neck projecting from the can top or breast portion.

Figure 3 is an enlarged fragmentary sectional view showing the nozzle in the process of being inserted upwardly through the mounting neck.

Figure 4 is an enlarged fragmentary sectional view illustrating the mounted condition.

Figure 5 is a horizontal section through the mounting neck and looking down at the dimple arrangement effective to prevent rotation of the nozzle in the neck.

In the example of embodiment of the invention herein disclosed, the improved nozzle mounting is shown incorporated in a container structure including a body 5 having a top or breast 6 secured thereon by a conventional double seam '7.

The nozz e to be mounted preferably is molded from a States Patent Q deformable plastic, such as polyethylene, to include a tubular body 8 externally threaded at 9 and having an outwardly projecting abutment and protecting flange 10.

The container breast is equipped with an upstanding neck 11 having a juncture with the breast 6 through a smooth curve at 12. The neck terminates at its upper end in an inturned edge 13 defining a nozzle receiving opening 14, and the breast wall portion outwardly of or surrounding the neck 11 is provided with a plurality of equidistantly spaced dimples 15 inwardly indented therein as shown in Figures 2 and 5 of the drawing.

In forming a mounting composed of the polyethylene nozzle of Figure 1 and the breast neck of Figure 2, the nozzle is inserted upwardly through the neck to bring about a firm seating of the flange .10 against the juncture of the neck and the breast and an indenting of the breast dimples 15 into the nozzle flange, as clearly illustrated in Figure 4. In other words, as the nozzle flange is firmly pressed against the inner wall portion of the breast, the dimples 15 will deform the flange and form recesses 16 therein. Also, the inwardly turned neck edge extremity becomes embedded or indented in the outer surface of the nozzle body as indicated at 17 and serves to secure the firm contact of the flange 10 against the inner surface of the breast and the indentation of the dimples 15 in the flange recesses 16 as illustrated in Figure 4. The indentation or embedding of the neck edge extremity 13 in the outer surface of the nozzle body prevents outward presentation of any raw metal edge portion, and the engagement of the lower edge portion of the nozzle against the juncture 12 of the neck 11 with the breast 6 serves to protect this portion of the breast and neck structure against exposure internally of any crazed or raw metal surface. The interengagement of the breast and nozzle flange portions at 15, 16 serves to secure the nozzle against turning within the neck as screw closure caps are applied on the nozzle.

While one form of the invention has been shown for purposes of illustration, it is to be clearly understood that various changes in the details of construction and arrangement of parts may be made Without departing from the spirit and scope of the invention as defined in the appended claims.
